Hogwarts: My Demon King System Rewards Chaos

My childhood was a blur of explosions, public humiliations for school faculty, and continuous \"accidents\" that earned me the title of Britain's most notorious delinquent. Everyone, from my high-ranking uncle to MI6, just wanted me gone. But these weren't accidents; they were system-fueled quests! Now, with a Hogwarts acceptance letter in hand, my \"Demon King System\" has upgraded, granting me an SS-tier wizard template and the legendary power of wandless magic. Chaos points? I'm going to make it rain. Dumbledore begs me to show restraint. McGonagall says I'm braver than the Weasley twins. Snape demands Azkaban. Even Voldemort now fears me. Hogwarts thought they knew chaos, but they haven't met their true Demon King yet.
